Patented July 12, 1932 MASSACHUSETTS, A CORPORATION OF MASSACHUSETTSSEPARATOR non TwIsTING AND SPINNING MACHINES Application filed May 21,1930. Serial b. 454,481.

This invention relates to separators for twisting and spinning machinesand has for one of its objects to provide a novel separator which hasspecial advantages when used in a twisting or spinning machine that isoperated in such a way that the cord being twisted or the yarn beingspun balloons to such an extent that adjacent balloons interfere witheach other.

Our improved separator is so constructed as to permit of this excessiveballooning of the cord or yarnwhile preventing the adjacent balloonsfrom interfering with each other. This end is secured by theconstruction of separator which allows adjacent balloons to overlapwhile maintaining them out of contact or engagement with each other.

lVe have illustrated the invention hereln as applied to a ring twistingframe but we wish to state that the invention is applicable to ringspinning frames or to any twisting or spinning frame which is beingoperated in such a way that the balloons formed about adjacent bobbinsare apt to interfere with each other.

In the drawings, Fig. 1 is a sectional side elevation of a portion of aring twisting frame equipped with our improved separa-tors;

Fig.2 is a top plan view of a portion of the frame;

Fig. 3 is a front view of Fig. 2;

In the drawings 1 indicates a frame portion of a ring twisting framewhich 1s equipped with a plurality of spindles 2. These spindles aremounted on the spindle rail 3 through the medium of usual bolsters 4:and each spindle is driven by a hand 5 which operates around a pulley 6carried by the spindle.

7 indicates the ring rail carrying the spinning rings 8 on which aremounted the usual travelers 9.

10 indicate the usual rolls by which the strands to be twisted togetherto form the cord 11 or the sliver which is to be twisted into yarn arefed to the machine, and 12 indicates the usual guide eye situated abovethe spindle and carried by the thread board the b 11 with 1 the spindlessituated yet itis straight in a 13 and through which passes to thetraveler 9. y

In the operation of twisting frames one of the factors which determinesthe size of the cord or yarn l1 spinning frames are usually manufactureda predetermined distance apart, which'is a sort of standard distance formachines of this type, and if it is desired to operate the machine undersuch conditions as to produce an increased ballooning of the cord 11 theadjacent balloons are apt to engage each other thus causing eitherimperfection in the twisted cord or possibly causing breakage of thecord.

As stated above we have .by our present invention provided a novelseparator to be used between adjacent spindles which will permittheincreasedor extra ballooning of the'cord 11 while preventing adjacentballoons from engaging each other.

Our improved separator is indicated at 15. This is made to have aconsiderable verticaldimension-as well as the necessary dimension fromfront to rear. The sepaapiece of in the same vertical plane situatedmidway between adjacent spindles but the intermediate portion is given ac'oncavo-convex form in a vertical direction thereby to pro- 'duce th e'concave face l6 and the convex face 17. While each separator has theconcavo convex form in the vertical direction 7 horizontal direction. heconcave face 16 and the convex face 17 thus have anesting relationwiththe upper and lower limits of the curved portion of each face occupyingthe same vertical plane. The separator may be carried in any suitable orusual way. As herein shown each separator is provided at its rear edgewith a stem portion having a horiz'ontallyextending foot portion 21which is attached to the rail 22 through the medium of asuitable bolt23. a

V The rail 22 is secured to bracket members 24: that are pivoted at 25to standards26... rising from the ring rail 7. The pivotal connection ofthe brackets 24 with-the standards 26 permit the rail 23 with theseparators thereon to be swung backwardlyfor removing or replacing thebobbins. e The manner in which the separators function will perhaps bebest seen from Fig. 3. The balloon formed by two adjacent cords 11a and11b for instance, 3, will engage the opposite sides of the separatorbetween corresponding bobbins and as shown in Fig, 3 the balloon of cord11a will engage the concave face 16 of said separator while the balloonformed by cord 11?) will engage the convex face 17 of said separator.The portion of thecord 11a which engages the concave face 16 of theseparator overlaps the portions of the cord 11?) that are situatednamesto this specification.

In testimony whereof, we have signed our JAMES E. FARRELL. JOSEPH 1.GAsKILL,

adjacent the top and bottom edges ofthe separator but these overlappingportions are heldout of contact with each other by means of theseparator. This particular separator with the opposite faces having anesting relation thus not only prevents the balloons from lashing eachother but it also allows the increased ballooning effect to take place.

The increased sizeiof theballoon formed in the cord 11a for instance maybe accommodated by the concave face16 of the separator while the convexface '17 accommodates the extra length of the cord 11?) between thetraveler is occasioned by the increased'ballooning effect. In otherwords, withollr improved separator each balloon is allowed tohave asufficient-size so that it Would normally interfere with an adjacentballoon and the portions of two adjacent balloons, which might normallyinterfere with each other, are maintained out of contact with each otherbut in overlapping vrelation.
